SPECIFICATION forming part of Letters Patent No. 380,379, dated April 3, 1888.

Application tiled July 2, 1887. Serial No. 243,215. (No model.)

In the axle is made a central channel or bore,

E, radiating from which to the periphery of said axle are numerous smaller channels, F. The outer end of the channel E is enlarged and threaded to receive the hollow cylindrical bolt G.

H, Fig. 3, is a bucket-wheel composed of ring or collar H, having on its periphery, and preferably cast integral therewith, the back etc I and .I, separated by partitions K and having their openings or months turned in opposite directions. The bucket-wheel H is fastened to the face end of the axle by screws L, which pass through the openings M, Fig. 3; hence said wheel is rotated by and with the axle.

Outside of the wheel H is secured a cover,

N, which is constructed as follows: Its upper front portion above the diametrical line and for a short distance below said line is enlarged to form a chamber, 0. Below this chamber at P the cover is simply a covering-plate. The central portion forms atube or sleeve, Q, having an inwardly-projecting flange, B. This 7 5 sleeve and flange fit upon the correspondingly-formed head of the bolt G. The lower plate portion, I, of the cover closes the front open side of the lower buckets of wheel H. The similar sides of the upper buckets coin- 8o cide with an opening, S, in the upper rear portion of the chamber 0, as best shown in Fig.

1. In the front and center of the cover N is a circular opening which is closed by the detachable plate '1. On each side of the periph- 8 5 cry of the cover N are lugs U, which bear against the adjacent projections II on the sides of the box 0. The mode of assembling these parts is as follows: The bucket-wheel H is placed against the face end of the axle and 0 there secured by screws, as described. The cover N is then adjusted in front of the wheel H. The plate T being removed, the bolt G is inserted through the central opening in the cover into the threaded aperture E. In order 9 5 to prevent this bolt from turning in the aperture E, after it is set up thereon, a smaller setscrew, V, Fig. 2, is inserted through the head of bolt G and into the axle. For convenience of introducing the bolt, two apertures, (b, are

To (ZZZ whom it may concern.-

Be it known that I, KARL ZALLUD, of the city, county, and State of New York, have invented a new and useful Improvement in Self-Oiling Boxes for Gar-Axles, of which the following is a specification.

My invention relates to a self-oiling box for the axles of railway-cars.

The principle of my invention resides in causing the rotation of the axle to force the oil through a central channel in the axle, whence it is ejected through numerous radial channels, also formed in the axle, and in this way made continuously to pass between the contactsurfaces of axle-periphery and journal-bearing.

My invention consists in the construction and arrangement of devices for carrying this principle into practical effect, andalso in the construction and arrangement of the packingring around the collar of the axle, which both prevent dust from entering the box and the oil from escaping therefrom, all substantially as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of my self-oiling box on the line :v w of Fig. 2. Fig. 2 is a horizontal section of the same on the lineYY of Fig. 1.- Fig. 3 is a front view of the bucketring whereby the oil is elevated in the manner hereinafter described. Fig. 4 is a transverse vertical section on the line Z Z of Fig. 1. Fig. 5 is a transverse vertical section on the line ZT of Fig. 1. Fig. 6 represents a modification in the construction of the end of the axle and of the devices thereto connected.

Similar letters of reference indicate like parts.

A is the axle, which in Figs. 1, 2, and 4 is shown with its journal end made in the usual form of car-axles in common employment.

13 is the journal-bearing, also of well-known form and arranged in the inclosing-box Gin the ordinary way. The box 6 is constructed substantially of the form shown, and is provided with a hinged door or cover, D, the opening in which is made large enough to allow of easy introduction and removal of the axle attachments, hereinafter described, so

that the said parts may be readily attached to and detached from the axle.

made in its head, wherein an ordinary twopronged key for turning said bolt may be inserted. Inasmuch as the bolt G is thus rigidly secured to the axle it turns with said axle and rotates freelyin the sleeve Q. The cover N,which is held in place upon the axle by the the oil being left entirely free.

bolt G, is prevented from turning with the axle by reason of the engagement of its side lugs, U,With the adjacent parts of the box 0. Finally, the plate T is fastened in place.

The oil is poured into the lower concave portion of the box 0 until its level is above the lower buckets of Wheel H. No waste or other absorbent material is put into the box, As soon as the axle begins to rotate, the lower bucket, having its open mouth in the direction of rotation, takes up oil. The oil thus taken up is carried around until the bucket reaches its upper position, when it discharges its oil through the opening S into the chamber 0. Meanwhile the bucket which was before the upper one is now the lower one and takes up oil in the same way, so that there is a continuous delivery of oil into the chamber 0 as long as the axle rotates. Oil is so rapidly carried into the chamber as to be forced therefrom at considerable pressure through the cylindrical bolt G and channel E and out through the channels F, thus passing and maintaining constant lubrication between the axle-periphery and the journal-bearing B. The oil then flows back into the box 0, wherefrom it is elevated, as before, by the bucket-wheel H, so that as long as the axle is in motion there is a constant flow of oil from the box through the axle between axle and bearing and back to the box. Inasmuch as the two sets of buckets I J, Fig. 3, have their mouths oppositelyturned, the same result will be produced when the axle turns in either direction, one pair of buckets, I, taking up the oil when the axle turns in one way and the other pair taking up the oil when said axle turns in the other way.

As the oil in the box 0 is. thus used over and over again, it becomes important to keep dust from getting mixed with it. So, also, inasmuch as no waste or other absorbent material is used in the box, means must be provided for efiectually preventing leakage of the oil therefrom. I accomplish both results in the following manner Ordinarily there is arranged around the collar of a railway-axle a packing of rubber or like yielding material, which suffices to prevent the escape of the oil already held in the cotton waste in the box. I remove this packing and substitute a wooden plate, I), having a circular opening in which is a brass lining-ring, c, which surrounds the collar. This plate is held between the boxfianges d e. The flange e extends around only the upper half of the axle-collar. Beneath this flange I place a loose wooden plate, f, having a semicircular opening also lined with a metal ring, 9. The upper ends of the plate f do not come in contact with the lower ends of flange d, an interval being left between said ends, as indicated by dotted lines, Fig. 1. The lower parts of both the plates 0 and f are received in a rear chamber, h, of the box 0. In this chamber, and immediately below the lower edge of plate f, is a leaf-spring, i, Fig. 5, which is bolted at its middle to the flat lower edge of said plate and has its ends bearing upon the bottom of chamber. The effect of this spring is to press the metal lining-ring g closely'against the under side of the axle-collar, by which means an oil and dust tight joint is produced. The front edge of the semicircular opening in plate f is beveled correspondingly to the slope of the lower portion of the box 0.

In the modification shown in Fig. 6 the hollow bolt G is omitted. A projection, j,-1s d rectly formed on the end of the axle. This projection rotates in a sleeve, K, formed upon the cover N. In order to secure the cover N upon the projection j,a cap-piece, V, the edges of which lap over the inner wall of the chamber O, is fastened by screws to the face ofthe said projection. There is a central openlng, m, through said cap-piece, com municatingwith the opening E- in the axle. 7

Among the advantages secured by my abovedescribed invention are the following: A con stant flow of oil is maintained between axle and hearing as long as the axle rotates, and this whether the axle turns in one way or the other.

This flow is maintained under considerable pressure, so that any danger of clogging of the channels is prevented. The same oil is kept in constant circulation, and is used over and over again; hence I can use less oil than is commonly employed. By reason of the pack ing device used, no oil can leak out of the box, nor can dust or other impurities enter it; hence the oil is always kept clean and free from grlt, and waste from leakage is prevented. The use of any foreign absorbent material for the 011 1s obviated. The parts of the oil-circulating device need be but four in number-namely, the bolt G, the bucket-wheel H, the cover N, and the plate or lid T, or, in the modification shown in Fig. 6, the bucket-wheel H, cover N, lid or cap-piece j, and plate or lid T. The bucketwheel H and the cover N may each be made in a single casting. All parts of the device are accessible, and may be attached or removed through the door D. They may be applied to any ordinary axle, in which the channels E F are easily drilled.

I claim 1. In combination with an axle containing a longitudinal channel and channels extending therefrom to the axle-periphery, and aj ournalbearing for said axle, a @X inclosing said axle and bearing and adapted to contain a liquid lubricant, a bucket-wheel-rotated by said axle, and a fixed chamber communicating with the longitudinal channel in said axle and arranged in proximity to the said bucket-wheel to receive the discharge thereof, substantially as described.
